Hiding should give you a better chance of staying hidden and you should also have a thing with the breathing like "X" to hold your breath, but the screen gets bluer the longer you hold it and if you hold too long you pass out and can't do anything for 5 seconds or something.

I was scared in this game when the jeff comes close to me.i did not really skared in that jeff screen.I only skared because you don't know - he's gonna kill you or you will survive. you have this feeling when you are hiding,or opening the door.
Cool story but short.
